Where Does Complexity Come From? (Big Picture Ep. 3/5)
This video is about the difference between complexity and entropy, and how complex things like life can arise from disorder. Thanks to Google Making and Science for supporting this series, and to Sean Carroll for collaborating on it!...

Second Law of Thermodynamics
In this video Paul Andersen explains how the second law of thermodynamics applies to reversible and irreversible processes. In a reversible process the net change in entropy is zero. In and irreversible process the entropy will always...

What is the Purpose of Life? (Big Picture Ep. 5/5)
This video is about how life arose and what its main function or purpose in the universe seems to be. Thanks to Sean Carroll for collaborating on it! This video is about how life arose and what its main function or purpose in the...

Can We Get Older Without Aging?
Nothing is guaranteed in life except death, taxes, and entropy. What do other life forms have to teach us about staying alive as we get old, and will we ever conquer death?

Are You a Boltzmann Brain?
Was an incredible drop in entropy responsible for the Big Bang? If that's the case, this would lead us to conclude that a great many other things are possible, including the likelihood that you are a Boltzmann Brain.

TED-Ed: Why don't oil and water mix? - John Pollard
Salt dissolves in water; oil does not. But why? You can think of that glass of water as a big, bumpin' dance party where the water molecules are always switching dance partners -- and they'd much rather dance with a salt ion. John...

Entropy of Gases and Gravity
Nobel Laureate Roger Penrose (Oxford) describes two different instances of the Second Law of Thermodynamic: expansion of gases and clumping due to gravity.

The Black Hole Entropy Enigma
Black Holes should have no entropy, but they in fact hold most of the entropy in the universe. Let's figure this out.

Practice Problem: Calculating Free Energy Change
We know that the free energy change associated with a process will tell us whether it is spontaneous or not. And we also know that this depends on the change in enthalpy and the change in entropy for that process, as well as the...

A Big Contradiction
Nobel Laureate Roger Penrose, University of Oxford, describes a profound puzzle that he's been wrestling with throughout his entire research career: how is it possible that the universe began in a peculiar state of both minimum and...

How We Use the Sun
Theoretical physicist and Nobel Laureate Roger Penrose (Oxford) describes how the sun's entropy is harnessed by all manner of life on earth.

Entropy explained - Why heat flows from hot to cold systems
Entropy explained. Intuitively understand entropy. Why Heat only flows one direction. Physics lecture with simulations of the system. The reason is because of statistics and more specifically multiplicity. We will explore how particles...

Solving the Puzzle of Black Holes: Hawking, Entropy, and a Theory of Everything
With the power of math, scientists are going even further, using equations to “look” inside black holes, peering at the central singularity where general relativity and quantum mechanics collide. PARTICIPANTS: Cumrun Vafa MODERATOR:...

Entropy and the Arrow of Time
As we experience it, time flows in a single direction. But entropy, and its description in the second law of thermodynamics, is one of the few physical phenomena to imply an actual arrow of time. Day 16 of our advent calendar:...
